Round Concho Shield Stampwork Ring by Calvin Martinez, Navajo, Size 8.5

Calvin Martinez, a Navajo silversmith known for his bold architectural forms, crafted this ring around a substantial round concho-style centerpiece with deeply impressed shield stamp patterns across a wide sterling silver shank. The concho form — a circular disc derived from Spanish colonial silverwork and adopted into Navajo tradition in the 19th century — is executed here at a scale that commands attention on the hand. Martinez's stampwork is precise and rhythmic, characteristic of the classic Navajo geometric tradition. Ring size 8.5. Available exclusively through Turquoise Mustang.
